The Alpha A7S (α7S / ILCE-7S) can read out read-out from the whole of the 35mm full-frame sensor. The camera outputs 4K (3840x2160) UHD video from the HDMI connector with 4:2:2 color sampling, for recording onto an external storage device or viewing on a compatible monitor. It also equipped with S-Log2 gamma that expands the dynamic range by up to 1300% to minimize clipped highlights and loss of detail in shadows.
